Solve using the elimination method. Show your work. If the system has no solution or an infinite number of solutions, state this.
11x + 8y = 103
22x – 7y = 68

    Double the first equation (on both sides) to obtain
    22x + 16y = 206

    Then subtract the second equation from the above (on both sides) to eliminate the variable x.

    23y = 138

    They solve for y.

    Then use any of the original equations to solve for x.

    Show your work for further assistance.
